Should you replace wires with WiFi in a small office?

Question

Computer networks

The floor area is only 60 sq.
Router RT-AC68U
Now everything is connected through switches, wired around the office. There is a desire to get rid of wires and plug WiFi cards into system units at 5Mhz. Like this or that .
What problems might arise in this case? There are 10-15 people in the office, all + - actively work with the Internet (surfing).

Answer 1

not worth it, the wires are still more reliable and stable

Answer 2

If there are stationary stations and are already connected by cable, then why bother? The cable is under the table and it is not visible. Will the user somehow notice visually that the cable is gone? For laptops, another story - the network cable is no longer under the table, but on the table. For aesthetics, of course, you can refuse. Well, if you use a gigabit network, then no WiFi will replace it.
I didn’t understand from the post, do you already have a router or are you just planning to buy one?
